THE DECLINE IN GERMINATION RATE FOR VEGETABLE SEEDS OVER TIME is AFFECTED BY SEED QUALITY, STORAGE CONDITIONS, AND SEED AGE.

THE YEARLY DECLINE IN GERMINATION MEANS THAT FOR EVERY PASSING YEAR, THERE IS A DECREASE IN THE PROBABILITY OF SEEDS GERMINATING SUCCESSFULLY, which CAN RANGE FROM 5% TO 10% FOR MOST VARIETIES of VEGETABLE SEED.
